Abstract
The current three-dimensional reconstruction algorithm of medical CT images still has certain drawbacks, and it is difficult to apply it effectively to clinical practice. In view of this, based on the parallel contour line, this paper studies the three-dimensional reconstruction algorithm of medical CT image, and realizes the three-dimensional reconstruction of the aortic dissection by surface drawing and volume rendering. At the same time, through the three modules of image preprocessing, aortic segmentation, dissection segmentation and three-dimensional reconstruction, the three-dimensional reconstruction of the patient's aortic dissection is realized. The reconstructed three-dimensional aortic dissection model can observe the shape of the internal sandwich model directly through the aortic wall, and the display of the three-dimensional structure of the interlayer is more intuitive and clearer. Finally, this paper designs experiments to analyze the performance of the algorithm. The research indicates that the three-dimensional reconstruction algorithm of medical CT images proposed in this paper has certain clinical effects and can provide theoretical reference for subsequent related research.
